IMPROVEMENT IN ORGAN-ACTIONS.

Specification forming part of Letters Patent No. 196,490, dated October23, 1877; application filed October 30, 1875.

The object of my invention is to indicate,

by a stop register or knob placed in the usual place, the condition ofthe swell and grandorgan stop-valves, when the same are operated by aknee or pedal lever, thus bringing directly before the operators eye thecondition or position of those parts, the same as all other stops ormutes are indicated.

By my drawings I show my invention applied to an oscillatingstop-register, and also to a reciprocating stop knob or register, and Ishow two different arrangements of levers, each a modification of theother, for accomplishing the result.

In the accompanying drawing my'invention is shown by two figures, asfollows:

Figine l is an elevation or direct front view of the parts. Fig. 2 is aplan View of the same. The right of each figure shows my inventionapplied to a reciprocating, and the left to an oscillating,stop-register.

B and B are the knee-levers, of which B operates the stop -registermarked swell, and B that marked grand organ, the registers for which areseen on the name-board. The knee-levers operate in the same way asusual. To communicate motion from them to the registers placed in thename-board or other usual place, I use the following arrangement ofparts: Beginning at the knee-levers, there exists in most organs, andespecially in those made imder patents granted to me, a system oflevers, connecting-rods, &c., reaching to the back part of the organ,for operating the swell and full organ. These parts are shown in thedrawing, as follows: connecting-rods D and D, tumblers E and E, mainlevers F and F. Now, if these parts do not exist in the organ, they ortheir equivalents must be supplied. At a convenient place on the mainlevers F or F, I attach a kind of tracker-pin, G or G, which operatesupon the arm H or H on a rock-shaft, h or h, which is placed back of thename-board, or back of the board upon which the registers are to bedisplayed.

\Vhen the register oscillates, as does L, Fi 2, it is attached to therock-shaft h,- but when it reciprocates, as does L, a connecting-arm, l,is used. For throwing the parts back in position when the knee-leversare released, I use the spring on or m.

If the actuating-lever to which. the trackerpin G or G connects has notsufficient sweep or movement, or if, at the point where connection isdesirable, it moves in the wrong direction, an auxiliary lever, I, canbe used, by which the necessary amount of sweep, orthe proper directionof motion, can be obtained.

What I claim as new is- In combination with the levers B, the rods D,tumbler E, levers F and H, and rock-shaft h, secured to the register Lor L, as and for the purposes mentioned.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

JOHN A. SMITH.
